I took this image 5 or 6 years ago using an amscope, canon 1000d, a piece of telephone book cover cut into a diy dark field filter, and a cheap camera/microscope adapter. I was surprised at how much detail showed up. It's from a sample of pondwater. Always been rather proud of this image. I posted it with the title "Dapnia 150x", but through the comments people left under the image I learned that it is not an actual Daphnia, but possibly several other breeds.
